c9e8fe53bc
Merged Age's changes and ripped out heaps of now obsolete stuff in the validator client.
- Replaced most instances of PublicKey with KeyPair, since they need to be passed into each validator thread now.
 - Pulled out a bunch of FreeAttestations, and replaced with regular Attestations (as per Paul's suggestion)
 - Started generalising pubkeys to 'signers' (though they are still just Keypairs)
 - Added validator_index into a few structs where relevant
 - Removed the SlotClock and DutiesReader from the BlockProducer and Attester services, since this logic is now abstracted to the higher level process.
 - Added a Hash trait to the Keypair (rather than just pubkey) which assumes the Pubkey uniquely defines it.

A first go at persisting validator keys and handling configuration. Addresses issue #253.
- Creates a keystore directory in the config
 - Fetches serialized keys from the keystore directory
 - If no keys, generates keys randomly, saves serialized keys to keystore dir.
